M62363FP
8-BIT 8CH D-A CONVERTER
DESCRIPTION
The M62363FP is an integrated circuit semiconductor of CMOS
structure with 8 channels of buil-in 8-bit multiplication type D-A
converters.
The input data is a easy-to-use 3-wire serial method and it is able
to cascading serial use with Do terminal.
The device is suited for use in automatic adjustment combination
FEATURES
•Digital data transfer method
3-wire serial data transfer method
•D-A converter system
Employment of the additional higher-order segment R-2R method
doubled precision compared to the convertional R-2R method.
•Short setting time
•4 Quadrant multiplication
APPLICATION
Convertion from digital control data to analog control data
for home-use and industrial equipment.
Automatic adjustment by combination with EEPROM and
microcomputer.(replacement of conventional half-fixed
resistor.)
